+The base library does not generate interfaces or abstract objects, but these enable you to generate mocks of them:

 ## Tips
 - ⚠️ Instantiating an `AutoFaker` takes a non-trivial amount of time because of Bogus `Faker` initialization (almost 1ms). It's recommended that a single instance be used if possible.
 - `AutoFaker.GenerateStatic<T>()` is also available, but should be avoided (as it creates a new `AutoFaker`/`Faker` on each call).
